Recommendation: Monitor — no exploitation signal at the moment.

Nextcloud Global Site Selector is a tool which allows you to run multiple small Nextcloud instances and redirect users to the right server. A problem in the password verification method allows an attacker to authenticate as another user. It is recommended that the Nextcloud Global Site Selector is upgraded to version 1.4.1, 2.1.2, 2.3.4 or 2.4.5. There are no known workarounds for this issue.
